Enhanced thermal shock and oxidation resistance of Si2BC3N ceramics through MWCNTs incorporation
Tóm tắt
Multi-walled carbon nanotubes (MWCNTs) reinforced Si2BC3N ceramics were prepared through mechanical alloying (MA) and following spark plasma sintering (SPS). The thermal shock resistance of Si2BC3N ceramics was evaluated comparatively through ice water quenching test and theoretical prediction. Furthermore, the oxidation resistance of MWCNTs incorporated Si2BC3N ceramics was evaluated under high temperature. The results show that the calculated parameters such as the critical thermal shock temperature (
